A coverb is a word or prefix that resembles a verb or co-operates with a verb. In languages that have the serial verb construction, coverbs are a type of word that shares features of verbs and prepositions. A coverb takes an object or complement and forms a phrase that appears in sequence with another verb phrase in accordance with the serial ...
A corepressor downregulates (or represses) the expression of genes by binding to and activating a repressor transcription factor. The repressor in turn binds to a gene's operator sequence (segment of DNA to which a transcription factor binds to regulate gene expression), thereby blocking transcription of that gene.
Transcription factor glossary; gene expression – the process by which information from a gene is used in the synthesis of a functional gene product such as a protein ...
A co-repressor is a molecule that can bind to the repressor and make it bind to the operator tightly, which decreases transcription. A repressor that binds with a co-repressor is termed an aporepressor or inactive repressor. One type of aporepressor is the trp repressor, an important metabolic protein in bacteria.
The ability of nuclear receptors to alternate between activation and repression in response to specific molecular cues, is now known to be attributable in large part to a diverse group of cellular factors, collectively termed coregulators and including coactivators and corepressors.
'The Schmied smith hämmert hammers das the Metall metal flach. flat.' Der Schmied hämmert das Metall flach. 'The smith hammers the metal flat.' Verbal resultatives This sort of resultative is a grammatical aspect construction that indicates the result state of the event denoted by the verb. English does not have a productive resultative construction. It is widely accepted that the be ...
In the reverse reaction, histone deacetylase (HDAC) removes the acetyl group from the histone tails and binds it to coenzyme A to form acetyl-CoA. Some coactivators indirectly regulate gene expression by binding to an activator and inducing a conformational change that then allows the activator to bind to the DNA enhancer or promoter sequence.
In linguistics, a verb phrase (VP) is a syntactic unit composed of a verb and its arguments except the subject of an independent clause or coordinate clause.Thus, in the sentence A fat man quickly put the money into the box, the words quickly put the money into the box constitute a verb phrase; it consists of the verb put and its arguments, but not the subject a fat man.
